Unipolar/bipolar steppers.

Hello i have quite a problem here. I ordered 6 steppers from aliexpress. but when they came i discovered 4 of these are bipolar and 2 are unipolar.
Now my question is, is it possible to make the board work with 4 unipolar and 2 bipolar steppers? Thank you and have a nice day.

If your unipolar motors have 6 wires (not 5) then you can use them as bipolar motors by leaving the two centre tap connections not connected. However, unipolar motors are often designed to run at higher voltages than typical bipolar motors, and that may make them unsuitable.

Hello thanks for fast responce. Sorry let me be more specific . I have two 6 wire 1.6amp unipolar motors (17HS4401) i was unable to find the voltage ratings. And four 4 wires 2.5amp bipolar motors (42BYGHW811B). My question is , can i use all of these 6 motors (2 of the unipolar in paralel for Z axis) on one board? OR am i screwed? Because i cant imagine trying to return something to China. Thank you very much and have a nice day.

Well i finally got to trying out the unipolar motors. I cant seem to make them work. Do i have to change something in the software side of things to make it work? So far the steppers just shake in one place.
Thank you for help

That usually means the phases are not connected in the correct pairs. How have you connected them to the Duet?

Well i did it the same way as with the other bipolar steppers. But whatever combination i use doesn't seem to work.

You haven't answered the question in a way that gives me enough information to make a suggestions. What I need is:

1. A link to the motor datasheet;

2. A photo of how you have connected them, or at least a description of the order in which you have connected the wires to the Duet's connector (assuming that the wires come straight from the motor, not from a connector on the motor).
